Batching System Needs Upgradation

I am a Manufacturer, When We produce a Batch we fill in the product in various sizes having same batch number. While the System does not allow us to create a single item with multiple sizes we have to add the same batch number to different items individually. Adding all the details for every batch like MRP, Selling Price, Purchase Price and all… that too repetitively for each item and every time. This is a cumbersome task to do. Your system seems to be only sellers friendly but not as much friendly for the Manufacturers who are manufacturing goods using Raw materials .
